CLAMP FOR HOLDING A CALK WHILE BEING WELDED TO A SHOE.

Specification of Letters'latent.

Patented Oct. 9, 1917.

Application filed. December 8, 1916. I Serial .No. 135,756.

To all whom it may concern:

Be it known that we, l/VILLIAM J. 1301.1. and LEOXIDAS L. KEMPTHORNE, citizens of the United States, and residents of Platteville, in the county of Grant and State of lVisconsin, have invented new and Im-' proved Clamp for Holding a Calk While Being IVelde-d to a. Shoe, of which the following is a full, clear, and exact description.

This invention relates to calk holders and particularly to an improved construction for holding the calk while the same is being welded to a horse shoe, and has for an object the provision of an improved construction whereby dilterent sized calks may be quickly and easily welded while the holder remains in the same position.

Another object in view is to provide a calk holder former with a socket and a rolling member whereby the two may properly act on a calk without becoming wedged against easy removal.

A still further object in view is to provide a calk holder in which the point or sharpened end of the calk will not be injured during the welding operation.

In the accompanying drawings:

Figure 1 is an end view of a calk holder embodying the invention, the same being shown in connection with part of an anvil.

Fig. 2 is a sectional view through Fig. 1 on line 2-2.

Fig. 3 is a transverse sectional view through Fig. 2 on line 3-3.

Fig. 4 is a top plan view of the holder shown in Fig. 1. 7

Referring to the accompanying drawing by numerals, 1 indicates a body provided with a socket 2, said socket having beveled walls 3 and 4: merging into straight walls 5 and 6. A roller 7 is arranged in the socket 2, preferably nearer one beveled wall than the other, as shown more particularly in Fig. 3, whereby calks of different sizes may be welded. The roller 7 may be mounted in different ways but preferably is journaled as shown in Fig. 2 in the ends 8 and 9, and is held against longitudinal movement by pin 10 extending into the groove 11. The body 1 is provided with a projection 12 which is designed to extend into an opening in anvil 13, whereby the holder is held in position ready for use. As shown in dotted lines in Fig. 3 the calk is pinched between wall at and roller '7 and is properly held in position without injury while the welding operation is taking place. If a smaller calk is to be placed in position the same is caused to engage thewall 3 and roller 7. It will be evident that the roller 7 permits an easy withdrawal of the calk after the welding operation while not injuring in any way the calk.

What we claim is:

1. A calk holder comprising a body hav ing a socket or chamber formed therein with a beveled wall on each side, and a roller arranged in said socket spaced from said, beveled walls and arranged parallel thereto.

2. A calk holder comprising a body having a socket or chamber formed therein,

having facing side walls and a roller extending from one end of the socket to the other, said roller being arranged longitudinally of said side wall and spaced therefrom.

3. A calk holder comprising a body having a socket therein having facing side walls extending longitudinally thereof, and a roller journaled inthe ends of said body and extending through the socket longitudinally of said walls, said roller being arranged nearer one of said side walls than the other whereby calks of different sizes may be operated upon.

4. A calk holder comprising a body provided with a projection for fitting the aperture in an anvil and a socket extending longitudinally of the body whereby substantially facing walls are produced and end members are provided, said Walls being beveled, and a roller fitted into said end members and extending through the socket, said roller being nearer one of said beveled walls than the other.
